Common use of Line 8 Protection Packages Clause in Contracts

Line 8 Protection Packages. The existing Line 8 relays cannot be reset to accommodate interconnection of the Small Generating Facility and must be replaced. The new Line 8 protection packages will both be step distance schemes. The ‘A’ package will use an LPRO 4000 and the ‘B’ package will use an SEL 311C. Interconnection of the Small Generating Facility will require the addition of DTT transmit and receive to the Xxxxx Solar Collector Substation. A new GARD 8000 shall be installed for communication with the Xxxxx Solar Collector Substation. DTT will be sent to the Xxxxx Solar Collector Substation for a line relay operation or R8 breaker failure. DTT for breaker failure will be received from Xxxxx Solar Collector Substation. A SEL 351-6 relay will be added for DTT receive supervision and will be used to trip and drive reclosing to lockout. The ACR reclosing relay shall be replaced with a SEL 351-6 to allow for the addition of drive-to- lockout (“DTL”) for DTT receive. (Note: Due to the addition of the Small Generating Facility, an area coordination study will be completed during final engineering and may result in resetting of relays in the area. The Interconnection Customer shall be responsible for all costs associated with this.)
